Application filed April 9, 1917. Serial No. 160,816.

Be it known that li, JAMns A. HALL, a citizen of the United States, residing at Liberty Mills, in the county of lVabash and State of Indiana, have'invented certain new and useful lmproveinents in Nut-Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the i Stllle.

This invention relates to improvements in 'nut looks and niore particularly to that type which contain in themselves a device for seof the bolt to be sawed ofi.

lVith these and numerous other objects in view, the invention consists of the novel features of construction, and the combination and arrangement ofl parts as will be hercinafter fully descrlbed and claimed.

In the accornpanying drawing:

Figure l is a Vertical section through a rail joint showing the appliance of my improvcd nut lock;

Fig. 2 is a detail horizontal sectionon the line of Fig. l;

lfig. 3 is a fragmentary perspective view of a portion of the nut;

Fig. 4- is a perspective view of the washer; and,

Fig. 5 is a sectional perspective View of the parts constituting the nut lock,

The device comprises a nut 1, of standard diniensions which may be constructed to fit standard bolts of any size and a washer 2 which has a plurality of sockets or reccsscs 2' placed circumfermitially thcrein about the center opening to ('.operate with the nut,

and with a fish plate of a rail joint or with an v other suitable base.

The nut 1 is provided with a cylindrical rccess 3 cxtcnding'longitudinally of the nut. A notched out seat 4 is provided on the inncr face of the nut l and communicates with the recess 3. A cylindrical tube or casing 5 of copper or some non-rusting material is provided with an outwardly projecting p the faces of the nut 1. A coil spring 8 is vopposite ends of the casing are flush with slidably mounted in the tube 5 and has one of its ends engaging the seat 7. A pin 9 of solne non-rusting material is provided' and has its greater length reduced as at 10. The head 11 of the pin 9 is constructedso as to provide a shoulder 12 on its inner face and is rounded on its outer face, the pin 9 beingv inserted through the tube 5, so that. the spring 8 engagjes the shoulder 12. A transverse opening 13 is cut through the reduced portion 10 at the end 'of the pin 9. 7 i

A cap member 14 of non-rusting material is provided and 'fits over the end of the 'redufced portion of the pin 9. Holes 15 ai'fek' ibored transversely through cap member, ,14

for the reception of the rod orl bar'16.,-

When the holes 15 are in aiinement with the'I hole 13, the bar 16 is pushed into Vplace andf bent at its ends to hold the parts together.v

It will be notedthat when the parts are in operative position, the head 11 of' the 9 will fill the opening in the inner face of the nut, and the cap member 14 Will cover'4 the opening in the outside face of said nut.

In operation, the rails 17 are placed in alinenient and the fish plates 18 fixed in place and the bolts 19 siid through the openings in said rails and fish plates. The Washer 2 is then placed over the threaded end of the bolt, with the soclrets or reccfsses 2' toward the outside. The nut is screwed on the bolt 'until it is tight and the spring pressed pin engzfages one of the recesscs in the washer.

To tako the nut off of the bolt, it is only necessary to pull out the cap member 14; and insert a spike or some other kind of rod or bar, between the outer face of the nut and' the inner face of the cap member 14:, and then 'nnscrew the bolt. lt will be seen that by pulling' out the cap member, the same will disengag'e the head 11 of the pin 9 from the rccess in the washer.

One of the most important features of this invention is the fact that the parts of and therefore Will not become locked by rust forming over the Operating parts, as do other nut looks. It will also be noted that the head of the pin and the cap member are so placed that the joint-s are not exposed to the air and therefore Will prevent water and moisture from entering the inner tubing of non-rusting material, thereby keeping the Operating mechanism always in perfect condition and ready for instant use.

As various changes in form, proportion, and in the minor details of construction may be resorted to Without departing from the spirit of this inventioinI do not Wish to be limited to the specific construction herein shown and described, other4 than as claimed.

I claim:- 1. The combination With a threaded bolt, a washer provided With soekets therein, a nut on said bolt, said nut having a longitudinal opening therethrough and a seat cut from one of its faces and communicating With said opening, a tube or casing of nonrusting material, 'a shoulder on one end of the same, said casing sliding into the opening through the nut, the shoulder on said casing engaging the said seat on the faee .of the nut, and a spring pressed plunger of non-rusting material in said casing for engagement with one of the sockets in said Washer for looking the nut m position.

2. In combination, a nut, said nut having i an opening-therethrough and parallel to the threaded opening, and a seat cut from its inner face and communiating with said opening, a oylindrioal tube or casing of nonrusting material tightly litting the opening, a laterally extending shoulder on the inner end of said casing to engage said seat, and an annular flange in thel outer end of said casing, a pin of non-rusting material, the inner end of said pin fitting tightly in said casing, said pin having its body portion reduced, thereby forming a shoulder and being slidable through said annular fiange and extending out beyond the outer face of the nut, said pin having a transverse opening therethrough at its outer end, a coil spring around the reduced portion of said pin, the inner end of said spring engagng the shoulder on said pin and the outer end of said spring engaging said annular fiange, a cap member'having socket in its inner face and a transverse opening therethrough, said oap member engagingthe reduced end of said pin so that the openings will register, and a looking pin through said opening, said cap member fitting fiush with and entirely coverng said casing to render the interior water tight.

I'n testimony whereof I have hereunto set my hand in the presence of two subseribing Witnesses.
